Media sharing with PS3

Does anybody know how I can do this? The PS3 is designed to work with windows media player, is there any mac software that will allow me to stream music to my PS3?

Thanks.

I read this in Mac life,

Medialink from www.Nullriver.com costs just 20 dollars and allows you to stream media from your mac to your PS3.

I got the 360 version from the same article, it works very well over my home network

I use twonky media player...works great and its free

i used the MediaLink as well, but since i've owned my Macbook Pro it doesnt want to work anymore...it starts playing movies then suddenly gives me a network error--on the PS3 end.
